Seismic attenuation in heterogeneous partially saturated rocks

We study wave-induced fluid flow effects in porous rocks partially saturated with gas and water, where the saturation patterns are governed by mesoscopic heterogeneities associated with the dry frame properties. The link between the dry frame properties and the gas saturation is defined by the assumption of capillary pressure equilibrium, which in the presence of heterogeneity implies that neighboring regions can exhibit different levels of saturation. In order to determine the equivalent attenuation and phase velocity of the synthetic rock samples considered in this study, we apply a numerical upscaling procedure, which permits to take into account mesoscopic heterogeneities associated with the dry frame properties as well as spatially continuous variations of the pore fluid properties. We consider numerical experiments to analyze such effects in heterogeneous partially saturated porous media, where the saturation field is determined by realistic variations in porosity. Our results indicate that the spatially continuous nature of gas saturation inherent to this study is a critical parameter controlling the seismic response of these environments, which in turn suggests that the physical mechanisms governing partial saturation should be accounted for when analyzing seismic data in a poro-elastic context.

Community Action in Iowa, 2005

The Division of Community Action Agencies is located within the Iowa Department of Human Rights and is the focal point for Community Action Agency activities within Iowa government. The Division of Community Action Agencies exists to develop and expand the capacity at the community level to assist families and individuals to achieve economic and social self-sufficiency, and to ensure that the basic energy needs of Iowa’s low-income population are met. The Division is comprised of the Bureau of Community Services, the Bureau of Energy Assistance and the Bureau of Weatherization.
